FIREPROOF WINDOW.

Specification of Letters Patent.

Application led June 8, 1910. Serial No. 565,825. i

city of New Rochelle, county of Westchester,

andl State of New York, have invented certain new and useful Improvements in Fire` proof Windows, of which the following is a speciication.

` This invention relates to improvements in reproof windows and refers more particularly to an anti-heatradiating window provided with double glazing `and ventilationand so constructed that in case of'lire the glazing remote therefrom will be maintained cool by the air between the glazings and thus` bar the progress of radiation through the window.

Among the salient objects of the invention are to provide a double glazed construction which has one ofl the glazings removably seated ina supplementary sash frame, detachably connected t the main frame, whereby saidv glazing or supplemental sash frame may be readily removed forcleaning or other purposes; to provide a construction ofV the above character which affords a free, unobstructed air passage between the two glazings whereby the `latter may be more etl'ectually protected against fire; to provide aconstruction in which the removable glazing while held positively within its sash frame in such a manner as to prevent rattling can nevertheless be easily removed when desired; to .provide durable weather proof construction which can be economically manufactured, and in general to provide an improved construction of the character referred to.

The invention consists in the matters hereinafter described and more particularly pointed out in the appended claims.

In the drawings-Figure l is an inside elevation of a tire-proof window embodying myinvention; Fig. 2 is a vertical sectional View taken on lines 2 2 of Fig. l and-looking in the direction of the arrows; Fig. 3 is a horizontal sectional view taken on lines 3 3 of Figrl and looking in the direction of the arrows; Fig. lis a detail view show- .ing the manner of constructing the detach# able inclosure caps; Fig. 5 isl a fragmentary perspective view of one end of the vertical members of the'sash frame. j

Referring to the drawings, 1` designates as a whole the sash frame which is or may be of well hollow sheet metal construction;

and 2 designates the vertical-muntin which 1s of generally similar construction. Be-

tween the muntin and the outer sides of the sash frame-are mounted the outer glazings 3, 3 which are seated between the grooves 4 and 5 in the usual manner. In constructions of this character it is not only necessary that a free and unobstructed air passage be formed between the double glaze, but also that one of the glazings may be removed in order that the lwindow may be more effectively cleaned. To this end, and as an important 'feature of the present-invention I detachably secure to the main sash frame ofthe window a supplementarysash frame designated as a whole-6. This supplementary sash frame comprises vertically extending members 7 and 8 secured by suitable bolts 9 to the interior of the main frame. Each of these vertically extending members ,.7 and 8 is provided with an inwardly eX- 'tending channeled seat 10 which extends throughout substantially the height of the window and is offset a considerable distance from the main frame, as shown more clearly in Fig. 3.

Each side ofthe respective channel members 10 is folded back upon itself as shown at 11. The crown of each of these folds at* the upper and lower ends of the latter is.'cut

away as shown at 12 to form jaws 13 which receive the inclosure or cap members'here inafter described. The inner sides of the supplement-ary sash members 6v are formed 4by a U-shaped muntin 15, which is detachsame way as the vertical members 7 and 8,

the sides being` folded back upon themselves in the manner-heretofore described andinratentee Aug. i, 191.1;l

the same way each of these cap members is .provided at its ends with jaws 19 whichiitl within the corresponding jaws on the-.verf

tary-casing may be riveted or otherwise sei-l1. cured 1n posltlon. The upper cap members j' 14, however, are detachably secured in place by means of screws or bolts inserted through suitable apertures 20 in the upper jaws 13 and 19. If desired, the cap members may be further confined in position by meansof downwardly extending lips 21 as shown.

In order to remove the inner glazings the upper cap members 14 are detached where- ,uponthe glazings may be readily slipped out of their channels. It is to be particularly noted that not only may the inner glazings be removed as described, but the supplementary sash frames themselves Vmay be-detached from the main frame., It is also to be noted that theinner and outer glazings are so spaced away from each other as t-o aord an unobstructed air passage 'which is entirely open at its ends.4 In conclusion it may be stated that the construction is such that by diverting the :radiation upwardly and consequently throughout the` 'whereby an open ended and unobstructed vair passage'is formed between said glazings,

oneof said supplementary members being detachably connected to the main frame.

2.' In a ireproof window, the combination with a marginal main sash frame having a. glazing iixedly seated therein, a supplementary sash frame secured to said main frame and having a glazing seat oilset and spaced away from the iirst glazing throughout its length, and a second glazing seated in said off-set seat, said parts being so arranged that the entire space within the twoglazings forms a free and unobstructed lair passage opening at both ends throughout .the width of the glazings.

'seat offset and spaced away from said glazing, an inner glazing seated on said seat and forming an open ended air passage between said glazings, and a removable end closure member forming a part of said inner sash fra-me and det'achably locking said inner glazing in position.

il. In a tireproo'f window, the combination with a hollow sheet metal main sash frame, of a muntin therefor, a pair of glazings seated between said muntin and the respective sides of said sash frame, asupplementary sash frame secured to Vthe main sash frame and having a glazing seat ott-set aconsiderable distance from said first glaz* ing, a supplementary muntin for said second sash frame and having glazing seats in alinement with the glazing seat of the sash, and a pair of supplementary glazings seated in the seats of the supplementary sash frame and its muntin, said parts being so arranged' as to form an unobstructed air passage be tween said glazings, said passage being open at either end throughout its width..l

5. 'In a vireproof window, the combina- .tion with alongitudinal main sash frame having a glazing seated therein, of a supplementary sash frame and supported by said first frame andhaving a glazing seat ott-set and spa'ced throughout its length from 'said first glazing, a supplementary glazing'aseated in said olf-set seat whereby an open en/ded air passage unobstructed throughout its width is formed between said glazings, and a removable e'nd closure member detachably securing the second glazing in its seat, said closure member having telescopic engagement with the adjacent end of the supplementary sash fra-me.
